Explanation

Message Format Service (MFS) uses four control blocks: MID (Message Input Descriptor) for input format, MOD (Message Output Descriptor) for output format, DIF (Data Input Format) for input data format, and DOF (Data Output Format) for output data format. These control blocks define how messages are formatted between terminals and application programs. All four are essential components of MFS.
